Can anyone help clear me up on how exactly to measure exhaust port duration on a PV motor (PV closed). I can’t find anything under search function. Seems like a dumb question but, unless my power valves are way to far from the piston, it seems exhaust gas could escape downward out underneath the valve before the piston is even level with it. Image below if that helps clarify. Am I supposed to measure from when edge of piston is level with the first bit of opening on the PV or as soon as the gas can get between the gap? Because if the last part is the case it seems almost useless to have the valve, unless my valves are way out of clearance. Thanks!
